What else can I help you with?
What temperature scale has a zero its lowest temperature?
The Kelvin scale has a zero at its lowest temperature, known as absolute zero. At absolute zero, atoms and molecules cease to move, resulting in zero thermal energy.
What happens to molecues when they reach absolute zero?
At absolute zero, molecules come to a standstill and do not possess any kinetic energy. This means they stop moving and their vibrations cease, resulting in the complete absence of thermal energy. At this point, all molecular motion halts, making it the lowest possible temperature in the universe.
Is absolute zero the point at which a substance has minimal thermal energy?
Yes, absolute zero is the lowest possible temperature where a substance has minimal thermal energy. At absolute zero, the atoms or molecules in a substance stop moving and have no kinetic energy. This temperature is equivalent to 0 Kelvin or -273.15 degrees Celsius.
What happens at zero degrees in the kelvin scale?
At zero degrees Kelvin, also known as absolute zero, all molecular motion stops. It is considered the coldest temperature in the universe, and no physical object can reach this temperature in reality.
What happens if you touch absolute zero?
Absolute zero is the lowest possible temperature where particles have minimal motion. If you were to touch an object at absolute zero, the extreme cold would cause rapid heat transfer from your body to the object, potentially leading to frostbite or severe tissue damage. However, achieving absolute zero is currently impossible in practice.
Is the speed of molecules at absolute zero temperature becomes double?
No, the speed of molecules at absolute zero temperature is zero. This is because at absolute zero, there is no thermal energy present to cause the molecules to move.
How absolute temperature has been achieved?
Absolute zero has not been achieved, temperature is simply proportional to the speed of the molecules, and absolute zero is the temperature that corresponds to a molecule that is not moving at all. While it happens all the time instantanously, we cannot get groups of molecules to stop moving altogether. We have gotten molecules extremely close to that speed using magnets to pull energy from molecules.
What happens to molecules when the temperature reaches absolute zero?
by the laws of thermodynamics, nothing can ever reach absolute zero. Theoretically, molecular motion would stop. They would still be molecules, they would just not move.
Do molecules disappear at absolute zero?
No. They are as frozen still as they can ever be. It is said to be scientifically impossible to actually reach absolute zero.
What happens to the particles of water when you remove heat from the water?
The molecules of water slow down and eventually stop when you hit absolute zero.
When do molecules have the lowest amount of energy?
When they are the coldest that they can be is when they have the least energy. Absolute Zero is when molecules have no energy and are not moving, but it is impossible to get to that degree.
What state would oxygen be at temperature absolute zero?
At absolute zero molecules are not supposed to move, so in theory everything would be a solid
Point where all molecules stop moving?
In theory, all molecular motion ceases at absolute zero which is 0 Kelvin (-273.15 degrees Celsius). At this temperature, the molecules have minimal energy and stop moving completely. However, reaching absolute zero is not practically possible.
What temperature scale has a zero its lowest temperature?
The Kelvin scale has a zero at its lowest temperature, known as absolute zero. At absolute zero, atoms and molecules cease to move, resulting in zero thermal energy.
Why is it impossible for anything to be colder than absolute zero?
Temperature is a measure of the average speed of the molecules in what's being measured. The faster the molecules move the higher the temperature, and the slower the molecules move the lower the temperature. At absolute zero, the molecules in what's being measured are completely stopped. Since molecules can't move any slower than stopped, absolute zero is the minimum temperature.
What is meant by absolute zero temperature?
It is the coldest temperature. Nothing is colder than absolute zero. Scientists do know what happens in absolute zero because to get it to absolute zero, they have to put the object in something colder. But like mentioned above, nothing is colder than absolute zero. It is pretty much the end of the thermometer.
In theory what happens to water at absolute zero should it constantly expand to this point?
At absolute zero, water would freeze and form a crystal lattice structure as its molecules slow down and lose kinetic energy. The expansion that occurs when water freezes is due to the arrangement of molecules in the crystal lattice, not necessarily related to temperature.
